8.8
8
8.4
9

Explanation:

Step1: Set up proportion

Since the triangles are similar, the ratios of corresponding sides are equal. So, \(\frac{3.5}{7}=\frac{4.2}{y}\)

Step2: Cross - multiply

\(3.5y = 4.2\times7\)
\(3.5y=29.4\)

Step3: Solve for \(y\)

\(y=\frac{29.4}{3.5}\)
\(y = 8.4\)

Answer:

8.4
